The RCDT Reverse Osmosis Process

RCDT reverse osmosis is a cross-flow filtration process, i.e. driven by pressure: untreated water flows across an active layer (membrane) at high velocity and the filtrate flow passes through the membrane in vertical direction.

Membrane separation is a quite physical process, i.e. the components to be separated undergo neither thermal, nor chemical, nor biological changes. Reverse osmosis allows the separation of low-molecular substances and inorganic salts.

Usually, RCDT reverse osmosis is operated up to 90 bar. In addition Rotreat offers a special high pressure technique up to an operating pressure of 160 bar, recovery rates up to 90% are possible. Reverse osmosis allows the separation of low-molecular substances and inorganic salts.

For this reason the RCDT reverse osmosis has proved its suitability in most different fields of application.
